Four types of evidence in a criminal investigation Essay

What are the four roles of evidence in a wicked investigation? A Evidence is any actual data (information), which smoke be presented in various forms. The actual data relevant to the sort out resolution of the case gutternister be obtained (determined) by the court by explanations of the parties, third parties and their representatives, affirmation, written and somatic evidence, expert opinions. Basic types of the evidence nominate corporal, documentary, demonstrative, and a testimony kind. The evidence is a type of information concerning certain(prenominal)(a) issues received by the investigatory process. Physical evidence is a type of evidence is an actual bearing that can be touchable and investigated. documental evidence can be in the form of a letter, receipt, testaments, and so forth Photos and videos or chats can present demonstrative type. Witnesses usu entirelyy deliver testimony kind of evidence.What are individual indications? Give an example of an individu al indication? A Individual characteristic is a type of evidence that presents an induvial commentary of a certain object. Here an expert takes into consideration while examining a certain subject, particularly evidence. All attach, irregular features, and imperfections are taken into account. The deoxyribonucleic acid can present a bright example of an individual characteristic. desoxyribonucleic acid profile from a bloodstain can present one of the multipurpose and prodigious types of evidence in a criminal investigation procedure.What is the difference mingled with individual characteristics and class characteristics? A An individual characteristic is usually base on the analysis of certain objects. This particular object is investigated, and its main marks and features are described. On the contrary, a class characteristic is a characteristic presenting feature of a certain class of objects. It is related to a certain host. The second type of features, particularly clas s characteristics turned to be more useful and efficient in the investigatory process, as it enables to receive more data acting according to the exclusion method.What are physical and chemical substance properties? Give an example of each. A Each object, particularly evidence, possesses some properties enabling to identify this particular object within a variety of gettable ones. There two basic type of properties physical and chemical. Physical properties can be examined without the conduct of any experiments. Moreover, they cannot decide chemical properties of an object. To the physical properties of an object belong, for example, color and smell. Chemical properties can change the chemical features of a matter, and they influence molecular composition. These chemical features can undergo various reactions and change its characteristics. To this group of properties belong, for example, the reactivity of water, the content of liquids in blood, etc.What do forensic scientists do to collect and preserve soil samples? A The task of forensic scientists is to carefully collect soil samples and take them to the lab, maximally avoiding an influence of external factors. Their samples are really sensitive and proper(postnominal). The soil is a physical type of evidence, and it can change the influence of various factors. That is why an expert has to be maximally careful to receive exact and likely results. They have to try to maximally preserve the primary features of the evidence.Critical conceiveing questions wherefore do you think forensic scientists are so careful that the tests they do are sensitive, reproducible, and specific? What might happen if they were slight careful about this? A In my opinion, the task of the forensic scientists is to be maximally careful to preserve all the chemical data that the soil samples may enable to get. If they are less careful about their samples, the test results may be not very accurate. What is more, the samples may supply no info, which may be useful in the investigatory process.Which type of evidence do you think is nearly useful in an investigation? Why? A I believe the most credible and useful type of criminal evidence is a physical sample. Physical evidence includes material objects that have properties that reflect the circumstances of a crime in the form of traces, origin, etc. The information contained in material objects, transmitted through direct perception of the features of the subject is the most credible way to receive data that may apply to the investigatory process.Why do you think that forensic scientists continue to look for class characteristics accustomed their limitations? A The task of forensic scientists is demands the responsible attitude, as they need to provide the investigatory experts with the data, that may enable them to reveal a crime. A magnetic dip according to which they continue to look for class characteristics given their limitations turned to be th e most prolific. The reason for that is simple it enables to receive the data enabling to arrive the answer maximally quickly and effectively. For example, the characteristics of various types of guns can be use as a helpful tool in the determination of weapons employ by a criminal in the process of committing a crime.
